My opinion;
In 2017 there were far more Trump supporters on politics side than today, and the word "maga", was not commonly used. When you posted liberal memes, they would religiously dog pile you, like locust, with dozens of negative comments. You would swear, they communicated with each other, like a hive.
I remember top of page likes on politics side numbering in the hundreds. I also remember posting civil conversations with some of them. ( Can you imagine?)
In my opinion, only the most ardent, hardcore, extreme, true believers of Trump exist on politics side today.
